LIQUID-SOAP. DISPENSER.

to effect the delivery of the liquid material from the bottom portion ofsaid container.

In this class of devices it is usual to employ a container composed ofglass and a metal fitting for a dispensing valve, the container being.manufactured by the process commonly known as blowing the glass.

As is well known, blow glass containers vary in dimensions, and this-istrueparticularly in the case of containers an end portion of which iscontracted to produce a neck for the attachment of a metal fitting, theproblem being to so coordinate. the metalfitting and theconta-iner as tosecure a llqu d-t-ight joint at the bottom of said container and to alsoinsure the proper relationship ofv the n metal fitting to the glasscontainer. Moreover, in the practical operations connected with theproduction of the container, it is necessary to grind off the end. faceof the glass at the neck, but experience shows that even with thisprecaution a considerable variation exists in the end faces of. thenecks f of different contalners similar in design and a size, and,further, that it seldom happens that the lower end of thecontainer. isground off at a right angle, to the axis of said container as should bedone. 7

One partof this invention consists of means whereby the glass containerand the metal fitting are mutually adapted to each other in such amanner as to secure aliquidtight connection between the bottom part-ofthe container and the fitting as well as to compensate for variations inthe form and dimensions of the container. To these ends, the containeris provided with a neck the lower part of which is formed wit-hanexternal thread, whereas the fitting isprovided with an internal threadso as to enable said parts to be separably coupledby a screw connection.A compressible gasket is positioned at a suitable point intermediate thecontainer and the fitting for the purpose of securing the desiredliquid-tight connection, and in a preferred embodiment of the inventionthe neck portion of the container is novided with a shoulderintermediate the Application as, June 9,1919." Serial No. 302,972.

tacts the gasket, thus enabling me to securea true and even bearingsurface for said gasket in order 'to compress the latter by screwing thefitting into position, the finish or the physical condition of the glassat the bottom of the neck being immaterial so far as concerns theliquid-tight connection for the reason that said fitting does notcontact with the bottom face of the neck, hence it is not required thatsaid bottom face of the neck be ground off at right angles to the axisof the glass container.

Another part of the invention consists in means for precluding theremoval of the metal fitting from the container when the latter ismounted in the supporting member, and, further, to provide means wherebythe container may be attached toand dismounted from the supportingmember wlthout subjecti'ng said container to breakage or fracture duringthe performance of the mountin;; or dismounting operations.

To these ends, I construct the neck portlon ofthe container ma manner toproduce a plurality of collars one of which is of less diameter than theother so as to permit the ready movement of the valve fittings-andcontainer neck through thefsupporting member. The collar oflargerdiameter is formed with a male thread adapted to be screwed, intoa ;fcmale, thread provided within an annular part of the supportingmember,

.whereby the collar at the neck portion of the container may be attachedto the supporting member without permittingthe glassv body to come intocontact with the supporting member so that the container can be attachedand detached with a minimum risk of fracture.

The metal fitting for the dispensing valve is formed with a tubularmember and with an outstanding flange, and in assembling thefittingrelatively to the container this tubular member embraces thecollar of small diameter on the neck whereas theflange of said fittingis spaced by the interposed gasket with respect to the shoulderintermediate the two'said collars of the neck portion. In mounting thecontainer on the supporting member, the threaded collar is screwed intothe annular part until the flange of the fitting is in contact with theflange ofsaid annular part, as a result of which the eontainer has afirm bearing in the annular part ends of said neck, with Wl1lCl1shoulder conand the-flange of said metal fitting is so seated upon theflange of the annular part that said fitting or the valve cannot bedetached from the container during the period that the container isattached to the supporting member.

In this connection it is desired to state that the lower threaded partof the glass neck is free from contact with the annular supportingmember and, further, that the flange of the metal fitting is so seatedupon said annular supporting member as to utilize the elasticity of thegasket as a bufier in reducing the stresses upon the glassware whenmounted on the bracket.

Another part of my invention consists in the provision of means forlocking the container to the supporting member, and the same beingeffective in all variations in the dimensions of that part of thecontainer with which cooperates said locking means. To these ends, thecollar of large diameter is provided with a bevel on its upper face,which bevel is exterior to the collar and positioned well below thesurface of the container body. Cooperating with said beveled face is alocking member, preferably embodied in the form of a screw mounted in apart of the supporting member, and in one form this screw is concealedfrom access when in operative contact with beveled face of thecontainer.

Other features and advantages of they invention will appear from thefollowing de scription taken in connection with the drawings, wherein-Fig. 1 is an elevation, with certain parts in vertical section, of asoap dispenser embodying this invention.

Fig. 2 is an elevation of the lower part of the container detached fromthe bracket and illustrating the format-ion of the neck thereof.

Fig. 4 is a detail view, partly in section and in elevation, of themetalfitting for the dispensing valve.

Fig. 5 is a plan view of the fitting shown in Fig. 4:.

The container A is composed, preferably, of glasshaving a desired shapeand dimensions. Said container is preferably closed and flattened at thetop, as at a, in order that on dismounting it from the bracket F saidcontainer may be turned over and rest upon a table, or other surface,for filling and cleaning it, the flat surface a affording a firm bearingfor the container when inverted. Another advantage is that the containeris hermetically closed at the top and that it requires no cover for atop opening, thus attaining economy in the manufacture of the containerand dispensing with a separate cover, the latter in other styles of con-.metal stamping may be used.

tainers being composed of metal adapted to be locked in place andaffording an additional item to the cost of manufacture. The bottom partof the container is formed with a neck, indicated generally at B and inefiect consisting of two collars 6 Z), whereof the upper collar 6 islarger in diameter than the lower collar Z). The upper collar extendsfor an appreciable distance below the body of container A, and the outersurface of this collar at the upper portion thereof is formed to producean incline or bevelc sloping downwardly and outwardly from that surfaceof least diameter at the under portion of the container, see Figs. 1 and2. Said collar 6 is formed on its annular surface and below the bevel 0with an external thread .72 see Figs. 1 and 2. Incidental to the use oftwo collars b b of different diameters, a shoulder or ledge b isproduced on the neck, see Fig. 2. The smaller collar Z2 is provided withan external thread cl, the same extending preferably from the shoulder bto the lower edge of the neck B, the under face of which neck may befinished in any desired way.

The neck at the lower part of the container opens downwardly, see Fig.1, said opening being closed by a metal fitting C containing adispensing valve E, said fitting being of the kind shown generally in myprior Patent No. 1,235,913, and the said valve being constructed andadapted for operation as disclosed in said prior Patent No. 1,235,913,and in Patent 1,199,913, and reissued Patent 13,898. The fitting iscomposed preferably of a die casting although a As shown, said fittingcomprises a tubular body f, a depending boss f and a radial flange 6 atthe top edge of the tubular body. The tubular body is open at the topflanged portion 6 thereof, whereas the boss f isopen for the operationof the valve stem. Said tubular body f is provided with an internalthread g, corresponding to the external thread d of the container neck,whereby the fitting is adapted by a rotative movement to be screweddetachably to the lower collar 7) of the container neck B.

The containeris composed of glass and is produced in the manner usual inthe art' by blowing the glass, the container used in my invention beingprovided with a depending neck characterized by a form of constructionwhich includes the two threaded collars Z) Z) and a shoulder 6 the planeof which shoulder is intermediate the threads Z), d. It is usual in theproduction of glass containers with neck portions to true up the endface of the neck by grinding off the glass, said grinding operationbeing performed with more or less irregularity as a result of which thebottom or end face of the neck may or may not be in a plane at a rightangle to the vertical axis ofthe con' tainer.

D is a gasket composed of compressible material, the same consistingpreferably of rubber and the internal diameter of which correspondssubstantially to the diameter 9f the lower threadedcollar b of the neck.

Said gasket is fitted around the collar 11 and into contact with theshoulder 6 the latter acting as a seat for said gasket. The fitting C isscrewed upon the collar b for the upper flanged edge of said fitting tohave contact the neck B that when said fitting is screwed upon the neckso as to compress the gasket said fitting does not come into contactwith the end face of the neck B, see Fig.1, whereby any irregularity inthe plane of the end face of the glassware will have no effect upon theliquid tight connection between the glassware and the metal fitting, itbeing noted that the shoulder b is in' a plane substantially at rightangles to the axis of the container so as to constitute a trueand evenbearing surface or seat for the gasket.

l/Vhen the container is screwed into the bracket, the flange eof themetal fitting is in contact with a flange m of the metal bracket; inother words, there is no direct contact between the shoulder 5 of theglassware and the flange m of the bracket, but on the contrary, there isa metal to metal contact due to the engagement of flange 6 with flangem, the elastic gasket D being intermediate the shoulder b and'the flangem of the metal bracket. In the operation of coupling the glass containerto the metal bracket, the container is screwed into the bracket untilthe flange c of the metal fitting arrests the rotative movement, thegasket D serving as a butter or cushion between the glassware and themetal bracket.

The container is mounted detachably in a supporting member F, shown inFigs. 1 and 3 as a bracket, the arm 7 of which is integral with a faceplate 71 and a ring 7', said face plate being attached in a suitable manner to a wall or other surface. The ring is formed with an internalthread is, corresponding to the external thread 5 of the neck, and saidring is provided with a flange m, the same being positioned at thebottom edge of the ring and extending inwardly with respect thereto andbeyond the plane of the internal thread in. The bracket is provided withan upstanding lug a, for suporting a container locking member herein'ahown as a screw G, although it is apparent other means may be employedfor retaining the container in a locked relation to the bracket. Thescrew is mounted in a thread provided within the lug n, and in the formshown the screw is adapted to be so positioned that its end portion isconcealed by and within the lug,thus precluding unwarranted access tothe screw and requiring the use of a suitable key G, see Fig. 1, for themanipulation of the screw in order to unlock and lock the container withreference to the bracket. 7

Assuming that the container is dismounted from the bracket and that itis desired to charge it with the liquid material, the container isturned over and placed on a table,

etcJ, resting upon the closed flat face a. The

metal fitting is now disconnected by a rotative movement in order tounscrew it from the neck B, thus permitting the fitting and the valve tobe taken off the container, The liquid material is nowintroduced throughthe opening in the neck, after which the gasket D is placed around thecollar 1) so as to "rest against shoulder 5 and the fitting and thevalve are replaced in order that the fitting may compress the gasket D.The

'fittingis screwed on the collar in a manner to tightly close the openneck of the con-' :tiner so as to render the latter substantially airand liquid tight. The container is now turned back to a normal positionand the neck, fitting and valve inserted into the ring j of the bracket,the container being rotated bodily forits external threads 6 to engagethe internal threads k of the bracket. The

rotation'of the container is continued until the flange e of the fittingcontacts with flange m of the bracket, the further rotation and downwardmovement of the container being "arrested by flange e occupying thebracket flange m, and the valve and the fitting protruding well belowthe bracket. The look i screw G is now rotated in the lug n for one endof the screw to have contact with the beveled face 0 of the container,whereas the other end of the screw is concealed against access withinthe lug n, the rotation of the screw being performed by aid of key G, or

other appropriate tool.

It willbe noted that the container has a fiXed engagement with thebracket by reason of its threads 5 being in direct contact with thethreads and its shoulder 6 being in indirect contact with flange m ofthe bracket,

and,further, that it is locked to said bracket,

by member G, or its equivalent, thus precluding surreptitious removalvof the container. Again, the flange e cooperates with the flange m ofthe bracket in preventing removal of the fitting and the valve from thecontainer when mounted in the bracket; but to remove the container, itis necessary to withdraw screw Gfrom the path of bevel afand to unscrewthe container from the bracket, the fitting C and valve E being cleaningit withdrawable with said container in order to preclude any escape ofliquid material therefrom.

The parts of my new dispensing device may be manufactured economically,one reason therefor being that the glass container having one openingonly can be produced at a cost of one-half to two-thirds below the costof a glass vessel with openings at the respective ends, it beingnecessary to grind off one end portion only of the container, and nocover bein required for the top of the cont iner, so that the cost ofone grinding operation and of said cover are saved and, moreover, thecontainer is airtight at the upper end portion thereof. Again, thebracket and the valve are inexpensive in construction, while at the sametime these metal parts are substantial, durable and efficient.

Devices of this character are exposed to the accession of dirt andbecome quickly soiled in use, but in my device the container is readilydismounted from the bracket, thus permitting free access to the bracketfor and enabling the operator to dismount the valve and the fitting fromthe container, whereupon the container can easily be cleaned andrefilled and the valve can also be easily cleaned to remove any adheringforeign matter tending to clog up the valve, it being apparent that thevalve is exposed for repairs, if necessary. Moreover, no very accurateor nicety of adjustment is required between the fitting and thecontainer, or the container and the bracket, but when the container isscrewed into, or unscrewed from, the bracket the glass body of thecontainer does not come into contact with the bracket or any partthereof, thus minimizing the liability to breakage on the part of thecontainer when mounting or dismounting it.
